Hop on Pop is a 1963 children's picture book by Dr. Seuss (Theodor Seuss Geisel). It was published as part of the Random House Beginner Books series, and is subtitled "The Simplest Seuss for Youngest Use". It contains several short poems about a variety of characters, and is designed to introduce basic phonics concepts to children.
This charming book introduces young children to words that rhyme, such as Hop and Pop, Cup and Pup, Mouse and House, Tall and Small. And once they have learned to recognize one word, children soon find to their delight they can read another simply by changing the first letter.
